Advantages

Both fast and stable

Autonomous switching between sensing modes: initial contact triggers a fast response from high-sensitivity sites, then stable sites take over for long-term reliability.

High directional accuracy

Achieves 99% directional recognition accuracy in underwater flow prediction, sufficient for underwater robotic obstacle avoidance and localization.

Stable over long cycling

Stable electrical output over 10,800 loading cycles, suitable for long-term deployment.
